I use to own 2 Kawasaki 4 wheelers and I have to admit they are a blast in the snow. and can be used all year long. mine was a 650 and a 700 prairie and went good in snow. but erie is a different story. if I just wanted something for ice fishing it would be a sled. but if I had the money for both and was fishing erie it would be on a sled. a sled is just more practical and much safer on water. if I didn't do a lot of riding my 4 wheeler all year long and I could only choose one it would be a sled. but a sled can only be used on ice and snow and I ride all year and I would get a big 4 wheeler and use studs.

I don't have my 4x4,s any more and don't ice fish up on erie. so im just giving my opinion on common sense. a sled just makes more sense on erie. but a 4x4 will work and you can find trails all over the country for riding in the summer. if you have no plans to ride all year then you should by all means get a good sled.
